Modified Slinky Seismometer

thingiverse

After working on the earlier Slinky Seismometer components I designed, I set out to create a simpler model. These components can be connected by 1/4-inch nylon threaded rods and secured in place with nylon nuts. It's essential not to use metal rods because the magnets within will be drawn to them, compromising the seismometer. More information about the TC-1 Slinky Seismometer is available here: http://tc1seismometer.wordpress.com To build a Slinky Seismometer using these models, you'll need to print the following minimum components: BaseRing.stl - This serves as the base and foundation of the seismometer. DamperRetainerRing.stl - This component houses the copper pipe acting as a damper for spring motion. It can accommodate either a 2-inch section of 1-inch diameter pipe or a 1-inch to 3/4-inch reducer coupling. WireSpoolRing.stl - Here, you'll wrap the copper wire for the pickup coil. The ring features wings where you can attach 6-32 screws acting as terminals. You should connect the wire from the coil to the top of the screw and then attach it out to the amplifier board located on the bottom. Choose between TopCap.stl or ExtendedTopCap.stl - This is where you'll attach the Slinky Retainer piece. TC1SlinkyRetainer.stl - The additional slinky coils are secured here, allowing for adjustments based on magnet position. You can print multiple copies of BasicSupportRing.stl for added stability. While short models might not require any support rings, having one every foot or so will provide optimal support. The connected rings utilize 1/4-inch nylon threaded rods and nylon nuts to hold them in place. Using nylon is essential because metal rods may either attract the magnet or introduce excessive damping - both of which are undesirable outcomes.
